    Biomass energy consumption, economic growth and CO2 emission in G-20 countries
    (Muş Alparslan Üniversitesi, 2019) Destek, Mehmet Akif; Okumuş, İlyas
    This study investigates the relationship between biomass energy consumption, economic growth, carbon dioxide emissions, and natural resource depletion in G-20 countries from 1992 to 2013. For this purpose, we used panel unit root tests, the panel cointegration test, the panel fully modified OLS (FMOLS) method, and the panel VECM Granger causality method. The results reveal that biomass energy consumption, economic growth, CO2 emissions, and natural resource depletion are cointegrated. In addition, increasing biomass energy consumption leads to increased economic growth. On the other hand, the increase in biomass energy consumption reduces CO2 emissions. Moreover, a unidirectional causality exists from biomass energy consumption to GDP growth, supporting the growth hypothesis. Finally, a bidirectional causal relationship exists between biomass energy consumption and CO2 emissions.

    Does pollution haven hypothesis hold in newly industrialized countries? Evidence from ecological footprint
    (Springer Heidelberg, 2019) Destek, Mehmet Akif; Okumus, Ilyas
    This study aims to investigate the validity of pollution haven hypothesis for the period from 1982 to 2013 in ten newly industrialized countries. For this purpose, we examine the relationship between real income, foreign direct investment, energy consumption, and ecological footprint using second-generation panel data methodology to take into account the cross-sectional dependence among newly industrialized countries. In doing so, the possible nonlinear relationship between foreign direct investment and environmental degradation is also searched. The results show that increased energy consumption and economic growth lead to increase in ecological footprint. Moreover, the U-shaped relationship between foreign direct investment and ecological footprint is confirmed in newly industrialized countries.

    An empirical note on comparison between resource abundance and resource dependence in resource abundant countries
    (Elsevier Sci Ltd, 2019) Shahbaz, Muhammad; Destek, Mehmet Akif; Okumus, Ilyas; Sinha, Avik
    This study explores the relative effects of natural resource abundance and natural resource dependence on economic growth for the period of 1980-2015 in 35 natural resource abundant countries. For this purpose, the relationship between economic growth, natural resource rents per capita, natural resource rents share of gross domestic product, capital, trade openness and financial development is examined. In doing so, we utilized with second generation panel data methodologies to take into account the cross-sectional dependence among countries. Our results show the existence of cointegration between the variables. Moreover, natural resource abundance promotes economic growth but natural resource dependence prevents economic activity. This study provides guidelines to utilise natural resources as economic tool to maintain economic development for longer period of time.

    Facing the challenge of alternative energy sources: The scenario of European Union countries based on economic and environmental analysis
    (Elsevier, 2024) Kartal, Mustafa Tevfik; Pata, Ugur Korkut; Erdogan, Sinan; Destek, Mehmet Akif
    This study evaluates the potential impacts of natural gas (NGC), renewable energy (RCC), and nuclear energy consumption (NCC) from an economic and environmental perspective for four European Union countries (Czechia, Finland, Hungary, and Germany), which have a reliance on Russia as well as use renewable and nuclear energy. In this context, quantile-based approaches are used; NGC, RCC, and NCC are considered as explanatory variables; and data between 1993/Q1 and 2021/Q4 is used. The findings show that (i) NGC has generally an accelerating impact on the economy and environment in all countries; (ii) RCC has a stimulating impact on the economy in Finland at all quantiles and in Czechia at higher quantiles. Also, it has a curbing impact on CO2 emissions in Czechia at all quantiles and in Hungary and Germany at the higher quantiles; (iii) NCC has an increasing impact on the economy in Hungary and Germany at higher quantiles. Besides, it has a limiting impact on CO2 emissions in Hungary at all quantiles, in Finland at higher quantiles, and in Czechia at middle quantiles; (iv) NGC, RCC, and NCC have a causal impact on both GDP and CO2 emissions. The outcomes imply that the impact of the alternatives on GDP and CO2 emissions varies by country, alternatives, and quantiles. RCC is the most suitable option for Czechia, NCC is the most suitable option for Hungary, and there is a trade-off for Finland and Germany. (c) 2023 International Association for Gondwana Research.

    The relationship between economic growth and carbon emissions in G-7 countries: evidence from time-varying parameters with a long history
    (Springer Heidelberg, 2020) Destek, Mehmet Akif; Shahbaz, Muhammad; Okumus, Ilyas; Hammoudeh, Shawkat; Sinha, Avik
    This paper re-investigates the time-varying impacts of economic growth on carbon emissions in the G-7 countries over a long history. In doing so, the historical data spanning the period from the 1800s to 2010 (as constructed) for each country is examined using the time-varying cointegration and bootstrap-rolling window estimation approach. Unlike the previous environmental Kuznets curve (EKC) studies, using this methodology gives us avenue to detect more than one, two, or more turning points for the economic growth-carbon emissions nexus. The empirical findings show that the nexus between economic growth and carbon emission seems over a long history to be M-shaped for Canada and the UK; N-shaped for France; inverted N-shaped for Germany; and inverted M-shaped (W-shaped) for Italy, Japan, and the USA. In addition, the possible validity of EKC hypothesis is examined for both the pre-1973 and post-1973 sub-periods. Based on this investigation, we found that an inverted U-shaped is confirmed only for the pre-1973 period in France, Italy, and the USA. These empirical evidences provide new insights to policy makers to improve environmental quality using economic growth as an economic tool for the long run by observing changes in the environmental impact of this growth from year to year.

    Renewable, non-renewable energy consumption and economic growth nexus in G7: fresh evidence from CS-ARDL
    (Springer Heidelberg, 2021) Okumus, Ilyas; Guzel, Arif Eser; Destek, Mehmet Akif
    This study investigates the effects of renewable energy (REN) consumption and non-renewable energy (NREN) consumption on economic growth in G7 countries with annual data covering the period 1980-2016 using a new panel data estimator that provides robust results under cross-sectional dependence, slope heterogeneity, and can be used whether series are integrated in different orders. In addition, the causality between the variables is analyzed with the panel bootstrap Granger causality method takes cross-sectional dependency and slope heterogeneity into account. According to Cross-sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) results, the coefficients of REN and NREN consumption are positive and statistically significant in both the short- and long-run. Furthermore, NREN consumption has a greater impact on enhancing economic growth than REN consumption. The panel bootstrap causality analysis reveals that the growth hypothesis (GH) is valid in REN in Canada, Italy, and the USA; neutrality is valid in REN in France, Japan, and the UK; the feedback hypothesis (FE) is valid for REN only in Germany. For NREN, the GH is valid for Canada, France, and Germany; the conservation hypothesis (CH) is valid in Italy and the UK. Finally, the FH is valid in Japan and the USA.
